Ok- I was in hurry and had a boat loaded with family ready to go skiing. I connected the battery and crossed the wires- plus to minus etc.. Needless to say, we didn't go boating- boneheaded!

1996 Prostar 190, nothing smoked and all of my gauges work. The engine turns over but I'm not getting ignition. I've checked the fuses at the top of the engine- all good. Battery wires functioning. Where could the problem be? I recall hearing about his before- a fried resistor in the distributor? Any help would greatly be appreciated!

Thanks. Yes- It has an ECM. I've had a mechanic look at it and he said it was the ECM. Supposedly, there are some diodes in the ECM that were damaged. I'm told that I will need a new ECM programmed by someone in California.

I don't have the same boat but my ECM did go bad all the sudden. I don't think I put the battery wire on wrong, it just stopped. I had MEFIBURN.COM flash my new ECM that I got from Crate Engine Depot. MEFIBURN.COM charged me $200 though, so maybe sending it to indmar for $45 is the way to go

The ECM does have some protection against reverse polarity but the ignition module in the distributor does not. The first things to go in a reverse polarity situation are the ignition module in the distributor and the alternator. I would make sure those are checked before replacing the ECM.
